What is the minimum distance between nitrification trenches in North Carolina?

The minimum distance between nitrification trenches in North Carolina is set at 9 feet center to center. This requirement is based on the need to ensure proper septic system functioning and the effective distribution of effluent throughout the system. Maintaining this distance helps to prevent any potential overlap of effluent dispersion, which can lead to localized saturation or contamination of groundwater.

By adhering to the 9-foot spacing guideline, septic systems can achieve optimal treatment conditions. This distance also reduces the risk of contaminating neighboring areas and helps ensure compliance with health and environmental regulations. Properly designed septic systems with the correct trench spacing contribute to the overall success of wastewater management and protect public health and the environment.
